APPARATUS FOR CURLlNG FEATHERS, 80C.

SPECIFICATION forming part of Letters Patent No. 643,861, dated February 20, 1900.

Application filed May 25,1899. Serial No. 718,288. (No model.)

To ctZZ whom, it may concern:

Be it-known that 1, Lotus BLUMENTHAL, a citizen of the United States, residing at New York, borough of Manhattan, inthe county of New York and State of New York, have invented new and usefullmprovements in Curling Apparatus or Machines, of which the following is a specification.

By means of this device articles such as feathers can be curled; and the invention resides in the novel features of construction set forth in the following specification and claims and illustrated in the annexed drawings, in which Figure 1 is a sectional side elevation of the curling apparatus. Fig. 2 is a plan view of Fig. 1, partly in section. Fig. 3 is a' front view of Fig. 1. Fig. 4 is a section along 00, Fig. 1. 4

On a suitable supporting base-piece 1 is a riser or standard 2. The table 3 is adjustable, having rods 4 sliding or guided in the standard and a screw 5 for setting the table to higher or lower level. Said base-piece is provided with a frame composed, as here shown, of a case or housing 6, containing various parts. Extending from case 6 is a shaft 7, which by pulley 8 or the like is rotated in the direction of the arrow 9. This shaft has a gear 10 which engages gear 11, so as to rotate the curler continuously in one direction.

The curler 12 is shown as a longitudinallyfluted stem extending from the rotary shaft 14, to which is secured gear 11. The rotation of curler 12, as indicated by arrow 15, is opposite to the direction of arrow 9. The curler 12 can be of any construction suitable for the purpose in hand.

The rotary shaft 7 is provided with a cam or disk 16, having the groove or cam part 17 and also an eccentric-pin 18. A sector 19 is shown with slotted arm 20, having pivot or bearing 21 on case 6. The pin 18, engaging the arm 20, will rock the sector back and forth. This sector 19 engages a slide 22 or its teeth 23, so as to rock the latter about the curler-shaft 14. This slide 22 is seated loosely on the sleeve 24 to slide longitudinally and oscillate or reciprocate thereon. The cam 17 moves the slide 22 longitudinally on the sleeve 24, which latter can rotate independently about shaft 14. The slide 22 can thus rotate roller-stud 29 in slide 22.

provided with ball-bearings about its circumference can rock easily in the case or bearing 6. This head 25 carries a fulcrum 26 of lever 27, having a fork or slot 28, engaged by This lever 27 carries what may be called presser-thumb 30. This thumb is a suitably cushioned or padded piece or block carried by arm 31, fulcrumed at 32 to lever 27. A spring 23 tends to press or hold arm 31 toward set-screw 34, and the tension of spring can be regulated by screw or nut 35.

The operation of the. device is readily understood. A feather, article, or other work is held or laid on table 3, while thumb is raised from curler 12,-the article being allowed to suitably extend onto such curler. The slide 22 being then moved by cam 17 backward or toward pulley. 8, the roller-stud 29, moving along incline or cam 28, will move lever 27 to move thumb 30 to curler 12. The article is now gripped between the curler and the thumb 30. The sector 19 now rotates the slide 22, so that the latter, with sleeve 24 and thumb 30, rotates with the curler 12 in the direction of arrow 15. The thumb having made, say, about one half a revolution with the curler 12, such thumb is moved by cam 17 and slide 22 away from the curler to release the article or work. WVhile in this release position the thumb 30 is rocked backward or in opposite direction to arrow 15, so as to be able to grip a fresh part of the work. After having swung to the curler or obtained a second grip or hold on the article the thumb again makes a partial or half turn with the curler 12. It will be obvious that the gear mechanism for operating the lever 27 is such that the thumb 30 is regularly rocked at timed intervals and the curler is rotated continuously. The cam 17 reciprocates the slide 22 by means of a rollerstud 37, Fig. 4, on fork-piece 38, slidable on shaft or cross-bar 39. This fork straddles or engages into the grooved hub of slide 22, as seen in Fig. 2, so that the fork 38, reciprocated by cam 17, will carry with it slide 22, while such slide can rotate freely in such fork. By

setting screw 34 lower or higher and adjusting the tension of screw 33 the cushioned presser-thumb 30 can be set as required with relation to the curler. The arm 31 could be rigid or one piece with lever 27; but a joint or adjustment, as at 32, has obvious advantages.

hen operating with this curling device on a feather, the quill or shaft of the latter can be laid either across the table 3 or along the table or on the bias, according as the quill is to be curled or the vane curled about the quill or other desired effects are to be produced with the plume or article. The curler 12 and thumb 30 being located together at one side of the table, the operator at the opposite side of the table can readily supply or manipulate Work on such table.

Vhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a curling-machine, of a base-piece, a supporting-frame thereon, a rotary curler-shaft supported by the frame and having a curler, a rocking thumb, a driven shaft, and devices actuated by the driven shaft to rotate the curler-shaft and curler and rock the thumb at timed intervals.

2. The combination, in a curling-machine, of a base-piece, a supporting-frame thereon, a rotary curler-shaft supported by the frame, a curler carried by the curler-shaft, a rocking lever, a thumb having an arm carried by the rocking lever, a driven shaft mounted in the frame, and devices actuated by the driven shaft to rotate the said curler-shaft, and curler and rock the said rocking lever at timed intervals.

3. The combination of a rotary curler-shaft, a curler thereon, a rocking lever, a. thumb cooperating with the curler and having an arm pivotally mounted on the rocking lever, devices for adjusting said arm on the rocking lever to vary the pressure of the thumb, and devices for rotating the curler-shaft and rocking said lever.

4:. The combination of a rotary shaft provided with a gear and a cam having a crankpin, a curler-shaft actuated by the gear, curler on said shaft, a sector rocked by the crankpin,a slide reciprocated by the cam and rocked by the sector, and a thumb swung and rocked by the slide, substantially as described.

5. The combination of a rotary shaft provided with a gear and a cam having a crankpin, a curler actuated by the gear, a sector rocked by the pin, a slide reciprocated by the cam and rocked by the sector, and a thumb having an incline or slot made to engage the slide, substantially as described.

In testimony whereof I'have hereunto set my hand in the presence of two subscribing witnesses.

LOUIS BLUMENTHAL. Witnesses:
